The sonic sickle erupted into a sonic oscillation after falling on the surface of the hard crystal.

A humming sound was heard, and the entire molten lake crystals trembled under the resonance.

The next moment, a crack opened on the surface of the crystal with a "click", and after a circle of spiderweb-like cracks broke out under Bai Yuqi's feet, it quickly spread in all directions, and with a "bang" sound, it turned into a pit of diamond-shaped broken crystals of the same size and shape!

Bai Yuqi, who was holding a sonic sickle in his hand, couldn't help but be dumbfounded, this dark red crystal condensed under the conflict between extreme heat and extreme cold looked very hard, and it was not something that ordinary metal could cut.

Moreover, crystals that can withstand extreme heat and cold are not as brittle as crystals such as glass.

So instead of using his eight-edged giant sword to try to cut through the molten crystal, Bai Yuqi took the Oasis Chieftain's scythe with the ability to sound and plan to try it.

But he didn't expect that the weakness of this seemingly hard crystal would be the sonic resonance, he just chiseled it lightly, and the sonic scythe did not even chisel out a white spot on the surface of the crystal, but was shocked by the impact of the sonic wave, which directly shattered the entire molten crystal.

Casually throwing the sonic battle scythe to the brain beast behind him, Bai Yuqi curiously picked up a palm-sized diamond-shaped molten slurry crystal block and studied it, and found that this thing contained an extremely large amount of inert dark energy, which made him dumbfounded.

Dark energy is a highly active repulsive superconducting energy, which has nothing to do with inert energy crystals.

Therefore, in the nature of the world of Etes, it is almost impossible to form dark energy crystals naturally.

But now, the dark energy has condensed into physical energy crystals in an inert state, which is too incredible?

"Could it be that the low temperature [of absolute zero], in the moment of the conflict between extreme heat and cold, froze the active particles of dark energy, causing it to be constant in the form of a solid entity?"

"No! It must have something to do with [Absolute Zero] reducing some of the dark energy to dark matter...... So it's not a dark energy crystal, it's a dark matter crystal!"

The appearance of dark matter crystals was a bit beyond Bai Yuqi's knowledge, and he could only speculate on the formation principle in a way that he could understand.

However, whether or not he could understand the formation principle of dark matter crystallization, it did not prevent Bai Yuqi from immediately realizing the value of this thing!

Although the dark energy contained in the dark matter crystallization exists in a stagnant inert state, if the inert energy in it can be drawn out in some way, it can be used as a stable and high-energy renewable energy!

Not to mention, this thing can completely replace the natural elemental crystals produced in the underground veins of Zhongnan Mountain, and use it as the energy core for constructing intelligent machines and dark crystal shields.

Under the same volume and density, the dark energy equivalent contained in dark matter crystallization is countless times that of natural element crystallization, and the gap between the two is like that of a battery car battery and a nuclear power unit.

Moreover, the repulsive superconductivity of dark energy also allows it to do work at the same energy consumption, which is also a geometric multiple of elemental energy!

Not to mention the endurance of energy supply, the dark energy of rotational expansion amplification, and the efficiency of absorbing and absorbing similar energy from the outside world, are also the geometric magnitude of elemental energy.

In addition, dark matter crystallization itself can produce dark energy, and before its own dark matter is exhausted, it can continuously convert dark energy as an energy source.

This allows it to be used even if it is taken to the Datang plane, but it is not as powerful as it was in the Havoc Plane.

The main thing is that this thing can be artificially made, unlike natural elemental crystallization, which can only be produced by relying on natural growth!

Although I don't know if this dark energy transformation mode can be reproduced in the future, after all, the spatial oscillation caused by the extreme heat and cold conflict just now is too coincidental.

But at the very least, he already had a huge lake full of dark matter crystals nearly 100 meters deep in front of him, which was definitely enough for Bai Yuqi to use for a long time, enough for him to carry out a comprehensive upgrade of the construction intelligence equipment under his hand.

In the past, although it was crystallized with natural elements, it could also be used as an energy core for constructing intelligent machines.

However, the elemental energy output by natural element crystallization is too "mild", so that the production of intelligent equipment can only be used as logistics construction, production and processing units.

And with the dark matter crystallization, Bai Yuqi can completely design all kinds of combat-type constructing intelligent machines, and maybe even the kind of Iron Man-style constructing intelligent machines that can really fly can be built.

Just a little thought, Bai Yuqi's brain hole was a little irrepressible.

The design of various energy weapons that use dark matter crystals as energy supply, and even the design of individual dark crystal shields kept coming to his mind, and he was ecstatic to quickly put the pool full of dark matter crystals into his dimensional bag.

This war for the unification of the Ash Wasteland has come to an end, and all that remains is to purge the remnants of the Oasis tribes and the Humanoid Alliance, and to collect the scattered tribes of the wasteland race.

This doesn't even need Bai Yuqi to pay attention to it personally.

Under the absolute superiority of combat power, there will naturally be the Ash Alliance warriors under his command to be responsible for completing it.

Bai Yuqi, on the other hand, took a large amount of dark matter crystals and returned to the laboratory set up in Ash City to carry out research, intending to use them as soon as possible.

After capturing the population of tens of millions of Oasis tribes, plus the equally large number of humanoid alliance slaves, the population of Ash City directly skyrocketed to more than 30 million, not counting the huge Blood Ape Clone Legion, the Regeneration Heroic Spirit Legion, the Spore Cyborg Legion and the Undead Scourge Legion under Bai Yuqi's command.

Such a large labor force directly pushed the construction of Ash City to an extreme, and countless buildings rose from the ground at a speed that was almost visible to the naked eye, forming an unprecedented huge city in a very short period of time.

Because of the barren natural environment and resources of the Etesian world, the wasteland tribes cannot afford the high concentration of overly dense population, and when the population of the tribe reaches a certain size, they can only choose to divide and migrate part of the population to other gathering places to survive.

However, this point is meaningless to Ash City, which completely relies on the "imported" resources of the Tang Dynasty for its survival resources.

Because the creatures of the world of Etes have a low demand for survival resources, so low that they can live by giving saliva to drink and nibbling on a little sand kudzu every once in a while.

So much so that the pressure on the transportation of materials in Datang time and space is almost ...... All they had to do was build a slide through the plane passage, and then keep cutting the ice from the Caspian Sea and sending it onto slide into the underground reservoir of Ember City.
